WARNING
Heater Expansion
It is a normal condition that during heat-up and cool-down a radiant
heater will expand and contract. Allowances for heater expansion
must be made in the gas connection and heater suspension. Improper installation, alteration, or adjustment can result in property
damage, injury or death.
WARNING
Gas Connection
Improper installation, connection, or adjustment can result in property
damage, toxic gases, asphyxiation, injury or death. Use an approved
stainless steel flexible gas connector (field supplied) to connect to the
gas supply to the heater in accordance with all local, state, provincial, and national codes
(ANSI Z223.1/NFPA 54 in USA; B149.1 in Canada) and as indicated in this manual.
WARNING
Venting
Inadequate venting of a heater may result in asphyxiation, carbon
monoxide poisoning, injury or death. This heater is indirectly vented
from the space. Venting must be in accordance with all local, state,
provincial, and national codes (ANSI Z223.1/NFPA 54 in USA; B149.1 in Canada) and as indi-
cated in this manual. Refer to Sections 11 & 12
WARNING
‘Smoke’ & Discoloration Condition
During start-up, the heating of material coatings used in the production process of the heater
may create a small amount of smoke during the initial period of operation. This condition is
normal and temporary .
Ensure that there is sufficient ventilation to adequately clear any ‘smoke’ from the space.
Notify site management and safety personnel to ensure that alarm system s are not unduly
activated.
Under certain conditions in some locations/environments, surface discoloration may occur on the
heater body where the products of combustion discharge from the heater. The discoloration is due
to the deposit of ambient air borne particulate or gases within the space that have passed
through combustion. The combustion of fuel gas in a clean environment will not cause any
discoloration. Surface discoloration does not affect the operation or performance of the
heater nor the manufacturer’s warranties.

WARNING
Clearance to Combustibles
Location of flammable or explosive objects, liquids or vapors close to the heater may cause fire
or explosion and result in property damage, injury or death. Do not use, store or locate flammable or explosive objects, liquids or vapors in proximity of the heater.
The clearance to combustible material represents the minimum distance that must be maintained between the outer heater surface and
a nearby surface. The stated clearance to combustibles represents a
surface temperature of 90F° (50C°) above room temperature.
It is the installer’s responsibility to ensure that building materials
with a low heat tolerance which may degrade at lower temperatures
are protected to prevent degradation.
In locations used for the storage of combustible materials, signs must be posted to specify the
maximum permissible stacking height to maintain the required clearances from the heater to
the combustibles. Such signs must either be posted adjacent to the heater thermostats or in
the absence of such thermostats in a conspicuous location.
In addition to stored or stationary material, consideration must also be given to moveable objects such as cranes, vehicles, and overhead doors, and structural objects such as electrical
and gas lines, electrical fixtures, and sprinkler heads.
Heaters must be located an appropriate distance from sprinkler heads. This distance may be
greater than the certified clearance to combustibles. Check the temperature rating of the sprinkler heads and locate heaters at a safe distance - in some instances the sprinkler heads may
need to be replaced by higher temperature heads.
It is beyond the scope of these instructions to consider all conditions that may be encountered.
Consult local authorities such as the Fire Marshall, insurance carrier, or safety authorities if you
are uncertain as to the safety or applicability of the proposed installation.
Refer to Figure 1 and Table 1 NEXT PAGE for the certified clearances to combustibles
for the appropriate model input/size.

The clearance to combustible materials represents the minimum distance that must be main-
tained between the heater and a nearby surface. The stated clearance to combustibles
represents a surface temperature of 90F° (50C°) above room temperature.
It is the installer’s responsibility to ensure that building materials with a low heat toler-
ance which may degrade at lower temperatures are protected to prevent degradation.
WARNING
In locations used for the storage of combustible materials signs
must be posted specifying the maximum permissible stacking height to
maintain the required clearances from the heater to the combustibles.
The signs must be posted either adjacent to the IR heating system thermostats or in the ab-
sence of such thermostats, in a conspicuous place.
For your convenience a “peel and stick” sign is provided with this heater.
Use a permanent marker to record the required dimensions on the sign.
To calculate the value ‘H’ ( Maximum Material Stacking Height):
Maximum Material Stacking Height: H = T (distance from heater to floor) minus C (the com-
bustibles clearance below the heater)
or H = T - C
Measure the on-site distance between bottom
of the heater and the floor = ‘T’ inches (cm).
Refer to Table 1 to get the value ‘C’ (clearance
to combustibles below heater) that corresponds
to the model you are installing
Subtract the clearance below the heater ‘C’
from ‘T’ to get value ‘H’ (maximum material
stacking height).
Enter this value ‘H’ on the sign with permanent
marker.
Then, for the heater model/size being installed,
refer to the information in Figure 1 and Table 1
to get the values for dimensions ‘S’, ‘F’ and ‘B’
(F and B are for ‘angle mounted’ heaters only).

Use for process or other applications that are not space heating will void the C.S.A. certification
and product warranty. Process application requires field inspection and/or certification by local
authorities having jurisdiction. Process application design should be provided by local experienced process design experts.
5. PRE INSTALLATION SURVEY
It is recommended that a full heating design including heat loss calculation be conducted on
the structure or area to be heated. Heater sizing and placement must consider available
mounting height, sources of greatest heat loss, and obstructions on the site. The certified clearances to combustibles with respect to stored material, moveable objects (cranes, vehicles, lifts,
overhead doors, etc), structural components, and sprinkler system heads. Consideration must
also be given to ventilation fan placement. Carefully survey the area to be heated, and for best
results place heaters in the coldest area(s) and at sufficient spacing to provide radiant heat
coverage.
Installation must conform with all local, state, provincial and national code requirements including the current latest edition ANSI Z223.1 (NFPA 54) in the U.S.A. and B149.1 installation
code in Canada, for gas burning appliances and equipment. The latest edition Electrical Code
ANSI/NFPA N0 70 in the U.S.A. and PART 1 CSA C22.1 in Canada must also be observed.

6. MOUNTING CLEARANCES
This heater must be mounted with at least the minimum clearances between the heater and
combustibles as shown in FIG-1, TABLE 1, Page 7. The clearances to combustible material
represent a surface temperature of 90 F° (50 C°) above ambient. It is the installer’s responsibility to ensure that building materials with a low heat tolerance which may degrade at lower temperatures are protected to prevent degradation.
Positioning of lights, sprinkler heads, overhead doors, storage areas, gas and electrical lines,
parked vehicles, cranes and any other possible obstruction or hazard must be evaluated prior
to installation.
Ensure adequate clearance around the air intake at the burner to allow sufficient combustion air supply to the heater.
6A. SERVICE CLEARANCE
: To allow servicing of burner and controls, provide a minimum
clearance of 24 inches (61 cm) from the gas supply / ignition-controls of the heater to a wall or
obstruction . (see Figure 2 below) - the minimum clearances to combustibles must always be
maintained.
For guidelines to heater placement refer to TABLE 2 (next page).
FIGURE 2: SERVICE CLEARANCE
7. HEATER PLACEMENT GUIDELINES
Models ecoSchwank-X & IL-X are approved for horizontal and angle mounting up to 30°.
IMPORTANT:
When angle mounting, the short axis may be rotated to a maximum of 30°.

8. VENTILATION
WARNING
Inadequate venting of a heater may result in asphyxiation, carbon monoxide
poisoning, injury or death. Heating system venting must be in accordance with
all local, state, provincial, and national codes (ANSI Z223.1/NFPA 54 in USA;
B149.1 in Canada).
This heater is approved for unvented (indirect venting) application. Ensure that there is adequate ventilation to supply combustion air and to dilute the products of combustion in accordance with all local, state, provincial, and national codes. A balanced exhaust / inlet air system
is required to ensure that a negative air condition is not created. See below for a summary of
exhaust capacity requirements by the national codes in the U.S.A. and Canada.
Air Supply: “Loose” buildings may not require any additional air supply if infiltration rates are
sufficient. However, for “tighter” buildings, or if air movement is stagnant in an area, air can
typically be supplied via inlet(s) with an area of 1 sq. in. per 1,000 Btuh input (22 sq cm per
kW). Locate air inlet(s) up at the level of the heaters to avoid cold drafts at work level, and effectively supply combustion and dilution air to the heaters and balance the system.
Heater Zoning: Exhausters are sized according to the input requirements of each controlled
zone of heaters. Multiple smaller zones are usually more effective in both comfort and ventilation control than one large zone. Maximum zone size is limited by the total input that can be
handled by the capacity of an exhauster, and by the proximity of the exhauster to heaters in the
zone.
Exhauster Location & Proximity: Exhaust must be located as high as practicable in the
structure above the level of the heater(s) to effectively dilute and remove the warm (rising)
products of combustion. The exhauster should be as centrally located as practicable in the
zone of heaters. Schwank recommends a maximum 6:1 ratio of the horizontal distance between the exhauster and the furthest heater in a zone, to the height the heaters are mounted
above the floor . For example, if heaters are mounted 20 ft above the floor, then the exhaust
fan should be located no more than 120 ft from the furthest heater in the zone. Sufficient air
supply must be provided.
Exhauster Capacity:
USA
: Natural or mechanical means shall be provided to supply and exhaust at least
3
/min/1000Btuh (0.38m3/min/kW) Natural Gas input of installed heaters [4.5ft3/
4ft
min/1000Btuh (0..43m
3
/min/kW) Propane input]. Some local codes may require an interlock to a dedicated exhaust fan. Consult your local code and ANSI Z223.1 latest edition
for all venting requirements and practices.
Canada
: It is required that the heater(s) be electrically interlocked to dedicated exhaust
fan(s) by means of an Air Proving Switch. Exhaust fan(s) must be sized to create 300
cfm (8.5 cu m/min) exhaust for every 100,000 Btuh (30 kW) or any fraction thereof of
total input of installed equipment. Provide combustion and ventilation air supply compatible with exhaust volume . Consult the latest edition of CSA.B149.1 Section 7.22.

9. GAS SUPPLY PIPING
WARNING
Install and connect gas lines in accordance with local, state, provincial and national codes (ANSI
Z223.1/NFPA 54 in USA; B149.1 in Canada).
Incorrect installation and connection of gas lines
may results in fire, explosion, property damage, injury or death
Do not install any gas piping or wiring in the heat zone directly above the heater.
Do not subject heater controls to leak test pressures when checking the main supply piping.
A. Gas piping must be sized to provide adequate input capacity to all heaters and appliances
in the system and at the pressure indicated in Table 3 below.
IMPORTANT:
Minimum supply line pressure at the inlet to the heater regulator must not be lower than 6.0 inches of water column pressure for natural gas and 11” w.c. for propane. The gas supply pressure must be
checked with all heaters in operation.
B. Provide a 1/8 in (3.2 mm) NPT plugged tapping, accessible for test gauge connection, im-
mediately upstream of the gas supply connection to the heater.
C. It is recommended to install an approved flexible connector between the heater and gas
piping - available as option from Schwank or from your local supplier.
D. A drip-leg prior to the inlet connection to the heater must be provided in the gas line.
E. On propane-fired units, a main line filter is recommended.
F. Piping joint compounds must be resistant to the action of natural gas or LPG
G. TEST FOR LEAKS: Apply soap suds solution to all connections and joints and if bubbles
appear, leaks have been detected and must be corrected. DO NOT USE A MATCH OR
OPEN FLAME OF ANY KIND TO TEST FOR LEAKS. NEVER OPERATE THE HEATER
WITH LEAKING CONNECTIONS. Leak test according to local or national codes.
DO NOT use pressure greater than 1/2 psig to pressure check the heater.
The supply system should be checked first with heater turned “OFF” followed by another
check with heater turned “ON”.
WARNING
GAS CONVERSION
This heater may be field converted from one fuel gas to another (natural gas to or
from LPG). Conversion must be accomplished with a kit available from the manufacturer. Contact your local distributor for the kit that is specific to the model installed (SEE PAGE 31). Conversion may include changing of the air restrictor as
well as the orifice and gas valve spring. Follow the instructions supplied with the
conversion kit.
Gas conversion must only be done by a trained gas service technician, according

10 ELECTRICAL REQUIREMENTS AND THERMOSTAT CONTROL
All electrical installations must meet local codes and the latest edition Electrical Code PART 1
CSA C22.1 in Canada and ANSI/NFPA N0 70 in the U.S.A..
TRANSFORMER SPECIFICATIONS
Single heater requires 24 Volt, 60 Hz electrical transformer sized at 40 VA.
Multiple heaters in a zone are powered by a single transformer. The proper transformer is 24
Volt AC, 60 Hz, sized at 40 VA for the first heater plus 20VA for each additional heater in the
zone - round up the calculated value to the next higher available sized transformer. For example, four heaters in a zone require a transformer of : 1 x 40VA + 3 x 20 VA = 100 VA . It is not
recommended to install more than 12 heaters per zone.
PROPER WIRING POLARITY MUST BE MAINTAINED, particularly when grouping the heaters
in a zone. Total wiring distances of up to 200' must use minimum 16 gauge electrical wire, and
wiring distances of over 200' must use minimum 14 gauge electrical wire. The heater must be
electrically grounded in accordance with local and national electrical codes. Malfunction of the
heating system will result if the voltage varies by more than +10% or -10%.
The heater can be controlled by a line voltage thermostat, a 24 volt thermostat or “off-on”
switch. Total load of all heaters must be considered in determining the required contact rating
of the controlling thermostat or switch.

11. INSTALLATION
11.1 GAS VALVE ASSEMBLY TO VENTURI
1. Remove valve and heater from carton. Remove the three screws from each venturi collector
bell located on one end of the heater.
2. Slide valve onto collector bells and insert two vertical screws. Then install remaining four
screws.
3. To avoid possible damage to wiring connection, it may be advantageous to hang heater before connecting wires. Connect two gray wires to the flame sensors located by the electrodes. Connect the two spark-plug type high tension leads to the Electronic Ignition Control. If a thermostat is used, separate the two red wires that are twisted together and connect the thermostat between them. If a thermostat is not used, connect the red wires to the
positive side of the power source and the single blue wire to the negative via a switch.

11.2 HEATER SUSPENSION
A. Properly size and install ventilation as per Section 8, gas supply as outlined in Section 9,
previous page, and electrical supply as per Section 10 above.
B. Ensure adequate clearance around air openings into the combustion chamber
C. Suspended infrared heaters shall be fixed in position independent of gas and electric supply
lines. Hangers and brackets shall be of non-combustible material. Heaters subject to vibration shall be provided with vibration-isolating hangers. Suspension hardware must be of
adequate capacity to support the weight of the heater - see Table 4
D. Mount heaters to structure by using non-combustible mounting hardware such as that illus-
trated in FIGURE 4.
E. Mounting at an angle of up to 30° on short axis (long axis level): see Figure 5
FIGURE 4: TYPICAL MOUNTING HARDWARE (supplied by others)
Rotate on the short axis only - long axis must always be horizontal
The ‘center of gravity’ of the heater allows angle mounting up to 30°

must always be horizontal
G. In locations used for the storage of combustible materials, signs shall be posted to specify
the maximum permissible stacking height to maintain required clearances from the heater
to the combustible materials. SEE PAGE 8
H. Connect heater to the main gas line. To absorb gas line expansion, heater expansion, and/
or any vibration from the building it is recommended to use a 1/2" stainless steel flexible
connector correctly sized to handle the gas capacity of the heater (available as option from
Schwank or your local supplier) . The flexible gas connector must be formed into a smooth
‘C’ shape from the gas supply to the heater inlet.
I. Mount thermostat at desired location, away from direct infra-red rays of heater. If the ther-
mostat is located on a cold wall, place sufficient insulation behind the thermostat.
J. Test gas line for leaks by using gas pressure test and/or soap test and as per all local and
national codes. Ensure gas pressure meets the requirements outlined in Section 9.
K. When testing the main gas line pressure, ensure the gas shut-off valve is “OFF”, oth-
erwise damage to the combination gas valve can result.
L. Test fire the heating system by following the lighting instructions on page 19 and on heater.

16. SERVICE GUIDE
Conduct a maintenance inspection of a luminous heater at least annually, prior to the heating
season.
WARNING
property damage, injury or death. This heater must be installed and
serviced only by a trained gas service technician.
Procedure:
Improper adjustment, alteration, service or maintenance can cause
1. Inspect the exhaust fan and all ancillary devices for proper operation and test for leaks at all gas
supply connections. Replace worn parts and repair deficiencies.
2. Inspect the integrity of the heater and reflectors. Repair or replace any defective parts. Clean accumulated foreign matter from the reflectors and heater body.
3. During operation:
Visually inspect the ceramic burner tiles for cracks
A ‘bright’ line on the tile surface indicates a crack in the tile
Replace any cracked tile and seating gasket
A cracked tile is typically the result of physical impact – inspect the burner body for any
additional damage
Visually inspect the ceramic burner tiles for blockage by accumulated dust or foreign material
A dark spot on the tile surface indicates blockage of the tile.
Use low pressure air (less than 20 psig) directed at the tile surface - Avoid directing air
stream at the gasket material between tile and heater body.
4. Inspect the venturi tube:
Remove any accumulated dust or foreign matter - use low pressure air (less than 20 psig)
directed at the venturi. It is important that the flow of combustion air through the venturi not
be obstructed.
5. Check the gas supply pressure at the inlet to the gas valve (1/8” NPT tap):
Natural Gas: minimum 6.0” w.c. and maximum 14.0” w.c.
LPG: minimum 11.0” w.c. and maximum 14.0” w.c.
Remedy gas supply condition outside of these specifications.
6. Check the gas supply pressure from the gas valve to the heater manifold (1/8” NPT tap):
Natural Gas: 5.0” w.c.
LPG: 10” w.c.
Remedy manifold pressure condition outside of this specification by adjusting the pressure
spring on the gas valve
Ensure that the gas valve is operating properly and that no particulate matter is foul-
ing the seating of the valve and allowing gas leakage - replace valve if necessary.
7. Inspect operation of the electronic ignition system:
Refer to I&O Manual trouble shooting guide and sections relating to the Spark Ignition and
Flame Sensing.

19. SEQUENCE OF OPERATION FOR FENWAL DSI CONTROL
OPERATION
Upon applying power (24VAC) to 24V terminal, the control will reset, perform a self check routine, initiate full time flame sensing, flash the diagnostic LED for up to four seconds, and enter
the thermostat scan state.
HEAT MODE
Upon call for heat from the thermostat, 24 volts is supplied to TH/W, the gas valve is energized
and spark commences at both burners for the trial for ignition period (up to 24 seconds total).
When flame is detected during trial for ignition, spark is shut off immediately and the gas valve
remains energized. The thermostat and burner flame are constantly monitored to assure the
system continues to operate properly. When the thermostat is satisfied and the demand for
heat ends, the main valve is de-energized immediately.
MULTI-TRY IGNITION CONTROL
Should either burner fail to light, or flame is not
detected during the first trial for ignition period, the
gas valve is de-energized and the control goes
through an inter-purge delay. The control system
will follow this sequence three (3) times before
lock out occurs.
Recovery from lockout requires a manual reset by
either resetting the thermostat or removing 24
volts for a period of 5 seconds. Allow 5 minute
shutdown period before relighting the burner.
Valve relay lockout 4 flashes
MODE LED INDICATION
Internal Control
Steady On
Failure
Start up 1 flash
Flame with no call
2 flashes

Ignition Lockout 3 flashes
FLAME FAILURE-RE-IGNITION
If the established flame signal is lost from either burner while the burners are operating, the
control will respond within 0.8 seconds. After a 5 second inter-purge period, the high voltage
spark will be energized for a trial ignition period (remaining time after previous trials - up to 24
seconds total) in an attempt to relight the burners. If either burner does not light the control will
de-energize the gas valve. The Multi Try Ignition Control will make two attempts to relight the
burners. If either burner does not relight the control will go into lockout as noted above in
“Failure to light”. When flame is re-established, normal operation resumes.
FLAME FAULT
If at any time the main valve fails to close completely and maintain a flame, the full time flame
sensing circuit will detect it and flash an error code of 2.
FLAME CONDITION - FLAME CURRENT CHECK
Flame current is the current which passes through the flame from the sensor to ground. The
minimum flame current necessary to keep the system from lockout is .7 microamps. To measure flame current, connect an analog DC micrometer to the FC – FC+ terminals. Meter should
read .7 µA or higher. If meter reads below “0” on scale, meter leads are reversed. Disconnect
power and reconnect meter leads for proper polarity.
